Best Practices

Communicate with relevant building personnel and ensure that they understand the procedures for delivering prompt adjustments or repairs in response to system alarms or occupant complaints.

Trend the data for air temperature and humidity on an ongoing basis. This is not required for the credit, but will help confirm that conditions are falling within acceptable ranges. (See the Documentation Toolkit for an example.)

If a thorough commissioning process is also being pursued, these periodic measurement activities should likely be coordinated with that effort. A detailed

The protocol and equipment used to perform these measurements must comply with Section 7 of ASHRAE 55-2004. This part of the ASHRAE standard addresses evaluation of the thermal environment and describes the required steps and equipment to properly take these measurements.

Establish a strategy for periodic measurements of radiant temperature and air speed at least once a year. These measurements are typically performed in occupied spaces using handheld devices, such as a globe thermometer or infrared heat sensor gun to measure radiant temperature and an anemometer to measure air speed.

Establish a process for responding to system alarms and occupant comfort complaints with appropriate corrective action and in a timely manner. Regularly review thermal comfort conditions to identify opportunities for adjustments.

Use additional sensors if space use and configuration makes it likely that a single measurement point will not be representative. Use separate sensors for perimeter and core areas within a single HVAC zone and equip rooms with additional sensors if they experience internal gains or solar gains that are higher than average for the building.

Location of existing BAS sensors may not be adequate to meet the credit requirements, so you may need to install additional sensors.  

The maximum sample interval for continuous monitoring is 15 minutes.

All sensors must be positioned 4–72 inches above the floor.
